Description
Technical field
The present invention relates to the self-organizing networking in cellular network.More particularly, the present invention relates to the method for the self-organizing networking between the subscriber equipment being supported in cellular network, subscriber equipment and network node.
Background technology
Universal Mobile Telecommunications System (UMTS) is designed to one of G mobile communication inheriting GSM.3GPP Long Term Evolution (LTE) improves UMTS standard in third generation partner program (3GPP) with a project of requirement in the future such as reply in the frequency spectrum of such as more High Data Rate, improvement and the cost of energy efficiency and reduction etc.Universal terrestrial radio electricity access network (UTRAN) is the radio access network of UMTS, and evolution UTRAN (E-UTRAN) is the radio access network of LTE system.
?
fig. 1 ashown in E-UTRAN in, subscriber equipment (UE) 150a-b is wirelessly connected to and is commonly referred to as eNodeB (eNB) and evolution radio base station (RBS) 130a-b being sometimes at random called WAP (wireless access point).ENB130a-b is directly connected to core network (CN) 110 through S1 interface, and is also interconnected through X2 interface.But in utran, radio base station or NodeB (NB) are connected to CN through radio network controller (RNC), and radio network controller is operatively connected to its NB.Therefore UE can use above-mentioned infrastructure mutually to communicate.
In its simplest form, wireless self-organization network is made up of with the stand-alone wireless node forming network dynamic formation connection each other.In so-called foundation-free infrastructure mode, self-organizing network does not require any centralized infrastructure such as such as UMTS or LTE system etc., and can based on recent technological advances discovery mechanism and each node decision-making, be used in the distributed algorithm realized in self-organized network nodes, " voluntarily " increases or reduces.For making radio node form self-organizing network, needing to allow node to carry out the standardization agreement collection communicated, especially needing the qualification process being beneficial to and setting up secure communications links in self-organizing network.
Many different wireless technologys can be used to form self-organizing network, and bluetooth is one of modal technology.Bluetooth ad-hoc network the simple and easy pairing of use safety (SSP) agreement can exchange and carry out device discovery, connection establishment and the necessary message of exchange public safety key.In addition, SSP allows so-called I/O (I/O) capabilities exchange of the preliminary information including artis physical communication capability.
In wireless network in the future, as
fig. 1 bin schematically shown in, dissimilar UE may want when being connected to cellular network formed wireless self-organization network.Cell phone, laptop computer, with the device of wave point and personal area network (PAN) 150a-c should therefore, it is possible to form self-organizing network 160 and exchange message mutually to provide service.Such as, in file download (client-server or equity) application, UE can form self-organizing network to exchange large Voice & Video file and other digital content.In in real time application, the subscriber equipment near WAP (wireless access point) or RBS can serve as towards away from access point or RBS and the interesting via node receiving such as other UE of some radio or television program or other audio or video content.Owing to recognizing these demands, support based on UE to the Common wireless communication service of network service and the E-UTRAN served based on the self-organizing network that communicates of equity (P2P) UE to UE specifying in standardization body.This system is by hereinafter referred to as the self-organizing network in infrastructure mode.
Self organization ability is introduced UMTS standard external member to be conducive to based on user between the new service of P2P relation.In this P2P environment, not only cellular carrier provides wireless service to arrive subscriber, as long as and supply and demand of this type of service find existence each other, subscriber just also can provide service mutually.Such as, the client going to airport can provide blog radio (podradio), game, file distributing and other P2P to serve interesting peer-to-peer or find and serve from the pod radio of interesting peer-to-peer, game, file distributing and other P2P.
In existing wireless Ad Hoc standard and solution, there is the limited support to exchanging radio node ability (ability as relevant in the frequency band, carrier aggregation, location etc. with antenna configuration, support), this is because current wireless self-organizing solution is connatural in UE ability.Present solutions is beacon signal based on the foundation-free infrastructure mode being designed for self-organizing network and greeting (HELLO) message, and these message based notices to exist and wherein UE is poor efficiency under connatural situation in ability in resource at the UE with honeycomb and self organization ability.
As mentioned above the same, UE may by can in infrastructure mode self-organizing mode in the future mutually exchange scope wide many service, many RAT network that the UE range of receiving being similar to the different ability of permission of today is served widely.But, no matter be that certain is served or supplies certain service and be ready that the UE needs of formation self-organizing network are compatible to communicate with the mode of energy efficient with frequency spectrum in ability due to interesting reception, or even can communicate completely.Such as, be furnished with multiple antenna and the UE supporting closed loop multiple-input and multiple-output (MIMO) patten transformation, sky line options and MIMO order to adapt to should be able in ad hoc networks time utilize these abilities.In fact, the success of the self-organizing network in infrastructure mode will depend on that this type of compatible UE finds each other and operates in compatibility mode so that the ability of demand and the various service of supply.
If the incompatible UE of ability can form self-organizing network mutually, then incompatible UE can consume frequency spectrum resource, manages mutually to form self-organizing network, but it the most never causes any service to exchange.Such as, if form self-organizing network with the UE of incompatible audio/video coding/decoding ability, then they can not exchange audio/video content mutually.
Therefore, UE will need to notice its oneself ability, to find other the compatible UE with similar capabilities in all dissimilar UE.But, excessive energy and frequency spectrum resource can be required to all UE broadcast such information.In a word, problem in infrastructure mode self-organizing network finds the UE guaranteeing compatibility or " having the ability " can find mechanism each other in the efficient mode of signal resource, and the ad hoc network communication of frequency spectrum and energy efficient and service exchange energy are enough carried out.Specifically, UE participate in the problem of self-organizing network be find them to use radio access technologies (RAT), frequency band, carrier frequency, modulation and coding techniques (such as, OFDM or single carrier FDM), duplex method (such as, Frequency Division Duplexing (FDD) or time division duplex) and other ability, so that compatible with other node participating in self-organizing network.
In paragraph below, provide the more details about some dissimilar UE abilities.It should be noted, dissimilar and ability that is classification can combine in single UE.Such as, high-end UE can be supported in continuous carrier polymerization in up link and both downlink and MIMO and interference cancellation receiver.
the UE classification of 3GPP definition
In modern wireless cellular system, the scope of application is UE classification widely, and each classification is associated with a capability set.Such as, in 3GPPLTE system, in the 8th edition, specify five UE classifications, and introduce a more multi-class part as LTE evolution in distribution version subsequently.The parameter that UE class declaration is relevant with down link and uplink physical layer, as the buffer sizes of the maximum quantity of the supporting layer for spatial reuse, support, measurement capability, healthy and strong header-compressed ability and other functions many.
multiband and many RATUE ability
Even if most of UE of today also support multiple frequency band for identical radio access technologies (RAT).This driven by the interests of service provider, because single service provider can have the carrier wave in different frequency bands, and wants by performing load balance and efficiency utilization carrier wave on different carrier.The example known is the example of the multiband GSM terminal with 800/900/1800/1900MHz frequency band.
In addition, according to 3GPP standard, UE also can support the multiple RAT comprising 3GPP and non-3 gpp (such as, 3GPP2 or IEEE) both techniques.Such as, in interworking process and performance requirement, support the combination of any permission of following technology: GSM, UTRANFDD(Frequency Division Duplexing (FDD)), UTRANTDD(time division duplex), E-UTRANFDD, E-UTRANTDD, HRPD(High Rate Packet Data) and cdma2000.
Many RATUE also can support honeycomb and non-cellular technology, such as, and WCDMA and WLAN (WLAN) and/or bluetooth or LTE and digital broadcasting TV.To today, in any standard, do not specify interworking process to be supported in the mobility between 3GPP technology and WLAN.But, in this type of UE, the independence of multiple technology and also parallel operation can be still possibility.Such as, can support that the UE of GSM and WLAN can be used in using the voice service of GSM and uses the data, services (such as, browsing) of WLAN.
According to 3GPP standard, all UTRA and E-UTRA frequency bands are public.But, different frequency bands can use in the different areas, such as, the 700MHz frequency band (UTRA Frequency Division Duplexing (FDD) (FDD)/E-UTRAFDD frequency band 13) of specifying in 3GPP specification (being respectively used to 3GPPTS36.101 and TS25.101 of LTE and UTRAFDD) only uses in the U.S..But, some frequency band is general or at least extensively distributes in global most area.2100MHz frequency band (UTRAFDD/E-UTRAFDD frequency band 1) such as uses in the most area in the whole world except America.Definite UE multiband and/or many RAT ability mainly drive by local market needs.Such as, the RAT supported for the UE of American market produce and market and/or frequency band can to a certain extent from be different for those RAT of Chinese market and/or frequency band.On the other hand, such as WCDMA and LTE etc. now or can be subject to the support of a large amount of UE the most at last in some technology of global deployment.But the frequency band of its operation still can be different.Frequency band 800MHz(UTRAFDD/E-UTRAFDD frequency band 5) and 1900MHz(UTRAFDD/E-UTRAFDD frequency band 2) such as can use in the U.S., and frequency band 900MHz(UTRAFDD/E-UTRAFDD frequency band 8) and 1800MHz(UTRAFDD/E-UTRAFDD frequency band 3) assign use in global most area, mainly do not comprise the U.S. and Japan.
carrier aggregation capacity
Carrier aggregation capacity allows UE to be received by multiple carrier wave and/or transmitted simultaneously.This can cause the many-side of data transfer rate to increase.Currently be the access of HSPA(high-speed packet) and LTE senior both the feature of standardization carrier aggregation.Carrier aggregation can be categorized as continuous or discontinuous.The latter can be subdivided in frequency band and between frequency band (or multiband) further.The UE with continuous carrier polymerizing power can receive data by multiple adjacent carrier simultaneously.On the other hand, multiband carrier aggregation capacity allows UE received by the carrier wave belonging to the different frequency bands such as such as frequency band 900MHz and 1800MHz simultaneously and transmit data.Carrier aggregation is also possible in the uplink, requires that UE can transmit data by multiple carrier wave simultaneously.
In HSPA is the 8th edition, be introduced through the down link continuous carrier polymerization of two adjacent UTRAFDD carrier waves.In HSPA is the 9th edition, agreed down link multiband carrier aggregation situation comprises: 850MHz/2100MHz, 900MHz/2100MHz and 1900MHz/1700MHz.More carrier aggregation situation is introduced in HSPA version in the future.For LTE, agreed several multiband carrier aggregation situation is to do further assessment.The situation that total total 12 differences corresponding to 12 different UEs abilities are discussed and decided.In the situation that these are agreed, even there is the polymerization belonging to three carrier waves of three different frequency bands (such as, 1800MHz/2100MHz/2600MHz).
antenna transmission and receiving ability
Another capability set comprises antenna transfer mode, as MIMO, cyclic delay diversity, beam forming, cyclic delay diversity, transmission diversity etc.E-UTRAN the 8th edition supports seven kinds of these type of antenna transfer modes.Similarly, transmission diversity scheme and MIMO scheme also exist in utran.In addition, the support to different receiver ability is also had.Such as in utran, four dissimilar UE receiver abilities are specified, as receiver diversity and the receiver diversity with inter-cell interference cancellation.
positioning method capabilities
Positioning service becomes very general, and expects that they are benefited from P2P service provision by favourable new innovation service.Such as, airline can to the passenger's bulletin waited on airport, and P2P canaster carried out at certain door in certain time, provided bonus points to winner.And for example, the high-end UE with accurate location information can to so accurate stationkeeping ability or be provided in the positioning service in down town or large exhibition area without other UE of stationkeeping ability.
Localization method can from being broadly categorized into satellite-based method and surface process, and they are further described below.
satellite-based localization method
GLONASS (Global Navigation Satellite System) (GNSS) is the standard technical term of the satellite navigation system making user can determine its position and obtain other related navigational information.Global positioning system (GPS) and European galileo navigation system are also the well known example of GNSS.But, only have that GPS is current to be in commercial operation, and runed more than 10 years.GPS comprises 24 to 32 constellations around geocyclic Medium-Earth Orbit (MEO) satellite.Their transmission are received by gps receiver and process to determine pilot signal and other broadcast message in geographical position.Signal from the satellite (such as, five or more) of some should be received so that gps receiver determines the geographical position of user exactly.
Assisted GNSS (A-GNSS) is the generic term for any satellite-based localization method, and satellite-based localization method is applicable to determine position and other relevant information, as the speed of UE.Assistant GPS (A-GPS) is suitable for UE, in the visible situation of the gps satellite of sufficient amount, makes UE subscriber in open area environment, can determine its position, time, even speed (comprising direction) more exactly.A-GPS standardization is used for UMTS.
A-GPS requires that cellular network (such as, base station or RNC) provides data, at least improves accuracy of measurement at the initial auxiliary UE with A-GPS ability, and reduces the time required in the position determining UE.Auxiliary data comprises reference time, visible satellite list, satellite signal Doppler, code phase and Doppler and code phase search window.This information is obtained by the gps receiver being positioned at serving BS, and it can detect navigation satellite more accurately.The Doppler search window size that can adapt to depending on UE and code phase, these data can within a few minutes (such as, less than five minutes) or longer time effectively.
When not having network assistance data, UE still can determine its position.Such as, but in the case, position will be so inaccurate in some cases, when less satellite is visible, or when weak from the signal of satellite reception.The acquisition of auxiliary data obviously requires UE elder generation and Network Synchronization, that is, reside on community.This means resident on community before, when weak from the signal of satellite reception, do not have the initial position based on GPS of the UE of effective or up-to-date auxiliary data to contain error.The error of position can between hundreds of rice be to two kilometers.
terrestrial positioning method
Have the terrestrial positioning method of several types, its signal using the radio network node such as UE and/or such as RBS to measure determines UE position.Some well known example of terrestrial positioning method are:
-based on the method for cell identity (such as, strengthen community ID).
-the network up link step-out time (U-TDOA) of the signal of different base station
-from the step-out time based on UE (OTDOA) of the signal of three or more communities
-fingerprint (fingerprinting) or pattern matching localization method
Certain methods such as based on these terrestrial positioning method such as cell identity and pattern matching location utilizes common UE nearby region measurement, as detect cell identity, reception signal strength signal intensity, path loss etc.When the method based on enhancing community ID, Web vector graphic community ID and additional more senior measurement, as the angle of arrival in base station and measurement of round trip time.What these were measured combinationally uses and greatly can improve positional accuracy.
On the other hand, some method such as such as U-TDOA and OTDOA requires specific measurement.Such as, OTDOA requires that the UE of the step-out time of the signal be called from multipair community measures.U-TDOA measures General Requirements and carries out three or more radio network node.

Embodiment
Below, the present invention is described in more detail with reference to some embodiment and accompanying drawing.For ease of illustrating instead of restriction, set forth specific details, as special situation, technology etc., to provide detailed understanding of the present invention.But, it will be apparent to one skilled in the art that the present invention can put into practice in other embodiment departing from these specific detail.
In addition, it will be apparent to one skilled in the art that illustrated function and parts herein can use the software that combines and work according to microprocessor or the all-purpose computer of program work and/or use application-specific integrated circuit (ASIC) (ASIC) to realize.Also will be appreciated that, although the present invention main in method with the formal description of device, but the present invention also can in computer program and comprise computer processor and be coupled to processor memory system in implement, wherein memory coding has one or more programs that can perform maniflest function herein.
With reference to special illustrative case, the present invention is described herein.Specifically, in the non-limiting general context relevant with E-UTRAN, the present invention is described.But it should be noted, the present invention and example embodiment thereof also may be used on the radio access network of such as other type such as UTRAN, WiMax and GSM.
In several embodiments of the invention, the solution of self-organizing networking (adhocnetworking) of UE is supported by infrastructure, solve the reciprocity UE identifying and be positioned at UE ability aspect compatibility in geographic area in the efficient mode of resource, and therefore make UE can set up the problem of self-organizing network, in ad hoc networks, they can utilize its complete potential and Exchange Service in ability.
Solution proposes so-called infrastructure mode, and in this mode, self-organizing network has the communication link towards the such as network of network such as LTE network or UMTS node.Can be such as RBS, RNC, the network node such as core network (CN) node or independent dedicated node keeps so-called UE capability database, database comprises the UE be interested in self-organizing of relevant network nodes support and the data of the ability that is associated thereof.The interesting UE forming self-organizing network will such as, when performing tracking area update, or when being switched to new RBS, register during ordinary selection in community in a database.This has been come by the network node that updates message to of the information sending the ability comprised about UE.
Therefore, in an embodiment of the present invention by the self-organizing networking of support UE is infrastructure.The basic element of character supported for this infrastructure is above mentioned UE capability database, but also has the ability information by mating the UE stored in UE capability database, is identified at the algorithm of the compatible UE in coverage.This algorithm will at hereinafter referred to as matching algorithm.Other parts for the support of self-organizing infrastructure are by network node multicast and are exclusively used in the class beep-page message of the UE of coupling.Therefore this message can may form the identity of the compatible UE of self-organizing network by therefore comprising, and for notifying the compatibility of these compatible UE identified about its ability.
The same as already mentioned, network node maintains the database that interest carries out the UE of ad hoc communication.This database also comprises UE ability, and is therefore called UE capability database.For certain geographic area keeps this database, geographic area can be such as overlay area or the tracing area of community, is similar to the paging in UMTS and LTE.If keep database by independent private network node instead of such as RBS, then this private network node can communicate, to transmit class beep-page message to compatible UE with other node such as such as RBS.Private network node can be configured to for various object, as the amendment for matching algorithm parameter through self-optimizing network (SON) node or operation and maintenance (O & M) function (also referred to as operations support systems, OSS).
By network node Operating match algorithm.A kind of mode performing coupling is described below.UE matching algorithm is identified at the UE of its ability aspect coupling or compatibility.The compatibility of different stage can be had.Incompatible UE(0 is compatible) can not communicate completely, the UE(1 that part is compatible is compatible) can communicate, but efficiency is not high or do not play its entire ability, and complete compatible UE(2 is compatible) can carry out efficiently communicating and utilize its entire ability.Usually, can define more multiple compatibility rank, in the case, UE can be I compatibility (I=0,1,2 etc.).
The ability that UE ability group must have according to the UE belonging to this ability group defines.The all UE belonging to this group can communicate mutually, and therefore, it is possible to form self-organizing network.There is the possible ability of One's name is legion, comprise radio access technologies (RAT) ability, band capability, transfer mode ability, receiving mode ability, dual-mode ability (TDD or FDD or both), header compress/decompress ability, carrier aggregation capacity, MIMO mode ability, stationkeeping ability, the service ability provided (is done one's best, alternately, stream transmits, in real time, game), subscriber equipment classification, the maximum of reception/transmission data, maximum data rate, the modulation type supported, the bandwidth supported, receive from a more than subscriber equipment simultaneously and be sent to the ability of a more than subscriber equipment, maximum transmission power level, delivering power class, to the ability that other carrier wave and RAT are measured, measure the ability of downlink channel status information and the location determining method etc. of support.Definite UE ability is defined by operator, and is that each UE configures (acquiescence).Human user can such as when upgrading the software of UE, or reconfigure each ability value when installing new opplication program or new interface etc.UE ability group also can be defined by operator.Such as, operator can determine three UE ability groups, and wherein each group is characterized by certain the value collection for ability, as
fig. 1 cin form shown in.The limited amount of the quantity due to group and the definition ability for each group, therefore, two UE being categorized into same group are not 100% compatibilities is acceptable.But they are in fact compatible and the likelihood ratio that successfully can form self-organizing network is much bigger under not having matching algorithm situation.Operator by adding more capable group, and can add more capable to this type of group each, makes matching algorithm more fine granularityization and more accurate and improve algorithm thus.
UE matching algorithm determines the compatible Grade I of new UE and each UE ability group.Therefore the output of matching algorithm be the new row in coupling form, as
fig. 1 dshown in row.Each field in new UE row specifies the compatibility levels (0,1 ... I) of this new UE and each UE ability group.If there be G group, then there is G the field corresponding to the row of this new UE.New UE is therefore, it is possible to belong to several group or (if in each field of row I=0) does not belong to any group in them.Such as, UE can belong to it communicate completely with it (I=2) group with it can with other groups several of its carry out communicating with limited efficacy (I=1), and it can not carry out communicate (I=0) completely with the UE belonging to other group.The example of UE ability is the RAT supported.0 compatible UE can be none identical UE of RAT, 1 compatible UE can be support direct UE-UE communication at least one of RAT (such as, bluetooth, WLAN or LTE-A++) identical UE, and 2 compatible UE can be the UE supporting that two or more RAT of direct UE-UE communication are identical.
Compatibility levels in coupling form also can be associated with time stamp.Time stamp specifies compatibility levels validity in time.Time stamp can be specify the absolute time time that is interval or " before x " or " after y " type.In addition, the compatibility levels of mating in form can be associated with positional information.Positional information can be such as absolute GPS coordinate and radius, or gps coordinate collection (determining with the region of the form of triangle or polygon etc.).

fig. 2describe one embodiment of the invention, Fig. 2 illustrates the network node that support self-organizing according to an embodiment of the invention networks and two UE(UE1 and UE2 schematically) between signaling flow.When interesting UE1 and UE2 carrying out self-organizing networking is triggered to register in UE capability database (DB), their transmission database update messages 210,220(are similar to tracking area update message) to network node.In an embodiment of the present invention, UE perform community reselect, tracking area update or switch time UE can be triggered to transmit this type of updating message.Alternatively, it can at any time be triggered to transmit updating message, that is, not necessarily when community reselects or when switching.UE at any time can transmit updating message automatically, or it can by the application triggers (further describing below) in UE.Another possibility is that network node at any time sends broadcast or multicast message to UE, asks them to transmit updating message.
The updating message transmitted comprises the ability information of UE, as the RAT of UE classification, support, the transmission dual-mode of support, the frequency band of support and/or above-mentioned other ability any.Updating message 210,220 can be Access Layer or non-access layer information (NAS).By RBS transparent transmission NAS, it can be the situation when the network node of management database is other node a certain outside RBS.The database update message 210,220 that UE1 and UE2 transmits also can comprise the information of the relevant application supported or service, UE actual position information or relevant UE in other embodiments and to be interested in the execution position of ad hoc communication and/or the information of time.The information of associated time can be such as time started of ad hoc communication, duration and end time, and it can be used in mating the UE wanting to communicate at about same time or carry out within the identical duration.UE positional information can be used for mating close to each other with the UE carrying out ad hoc communication geographically, this is because the short distance between UE makes communication more efficient in power consumption and radio channel quality, such as, therefore position for self-organizing networking can store in a database for information about with the time together with ability information, and can for adding time stamp for the compatibility levels in coupling form in matching algorithm, such as, as mentioned above.
Updating message comprise and the support of the relevant UE stored in capability database application or service information can use as described below.Suppose that UE1 can serve as database or the server of the information such as the translation comprising such as picture, film or books, and UE2 wants to retrieve this type of information.By mating UE1 and UE2 based on this information on services, can exchange message.
May add in updating message and be such as UE operating system or semi-static capability at the out of Memory of capacity data library storage, such as UE battery information or UE power consumption state.UE battery information can be represented at information (such as, stand-by time or air time) aspects such as the current UE power of battery and/or such as power of battery abilities.Can such as with such as (with or residue) watt constant power unit, represent the current UE power of battery with percentage or with ranks such as such as low, neutralization are full.UE battery power information can be used by different way by matching algorithm.Such as, when the UE power of battery reported is low, some other UE abilities can be limited wholly or in part.Such as, the use of MIMO ability can be limited to (2 × 1) MIMO instead of possible (4 × 2) MIMO.This means that this type of UE will be merely able to use two transmission antennas and a reception antenna, but according to actual antennas ability, it can use four transmission antennas and two reception antenna transmission and reception.In this particular example, matching algorithm can mate this UE and another UE that can accept from the data receiver of two transmission antennas to realize ad hoc communication.
In an alternative of the present invention, updating message can be received from another network node instead of from UE.This can be such as confirm in the reservation of UE the situation that self-organizing networks all the time.Therefore can store relevant UE ability in a network, and updating message can be transmitted from another network node subsequently.Such as, attaching position register (HLR) can transmit the eNB updating message to managerial ability database, or HLR can transmit and updates message to Visited Location Registor (VLR).Another example is when UE changes its registration zone (such as locating area or tracing area).The updating message of the UE stored in former network node can be sent to the new network node of reposition or the tracing area of serving this UE subsequently.As has been described, UE also can transmit when entering the new registration zone in such as location or tracing area etc. and update message to network node.In the case, UE can a translator unit information, as the information that can change in time, such as, and locating information, duration etc. for ad hoc communication.On the other hand, such as the static state such as UE antenna capabilities or semi-static information are received from old network node in updating message by new network node, and updating message generally can comprise the complete information collection relevant with UE ability.
In one embodiment of the invention, interesting carry out self-organizing networking however the current UE not residing in or be connected to network node by for transmit updating message with in database registration object temporarily access network come initiatively to register at database.Initiatively recording plan allows subscriber equipment subscriber to input it to support that other compatible UE or the alternative application program obtaining the preference of support from other compatible UE realize by using.In last situation, subscriber can obtain the remunerations such as such as bonus points.In a rear situation, the performance that subscriber can be only enhanced by increasing a little of cost.Application program also clearly can inquire subscriber's its UE abilities whether all or only subset or limited ability can be used in ad hoc communication.The use of limited capability means that such as only 20MHz bandwidth is for ad hoc communication, but the complete bandwidth ability of UE can reach 40MHz.Similarly, limited antenna uses and can imply that only use reaches two transmission antennas and carries out ad hoc communication, but UE can support nearly four transmission antennas.The advantage of the use of limited capability is that this can cause the process of reduction and/or lower power consumption at UE.Based on the input of subscriber to application program, UE such as by sending updating message as mentioned above, in automatic updating data storehouse, backstage.Initiatively registration can be carried out frequently, or carries out after the timer expires of UE data (being further described below).
Network node is receiving accessing database after updating message 210,220, and by the information received upgrade 230 it.Therefore database will comprise UE and the ability information thereof of all registrations, and may also have application or information on services, about the information of UE position or UE think wherein with the information etc. when be connected with other UE.It should be noted, UE capability database also can be positioned in other node a certain outside self-organizing network enabled node, just can as long as self-organizing network enabled node may have access to it.
When registering UE ability information in a database, start timer alternatively.Timer can be used for deleting untapped information in the time-out period of timer.This can be such as the situation of coverage of the RBS that the network node never entering management database at UE is supported, this be use above-mentioned initiatively register time possible case.May correspond to the value in pre-determining during timer expired, or it can by network node or UE or both be by the decision that intercoms mutually.
When UE capacity data stores in a database, network node runs the matching algorithm 240 of mark with the UE of matching capacity.In addition, such as position and/or timing for information about etc. can be provided and take into account at the out of Memory of database purchase in updating message in this coupling.
As has been described, matching algorithm is had can be used for the various modes of group of marking matched UE or UE.In its simplest form, matching algorithm only selects the UE belonging to identical 3GPPUE classification, generally in maximum uplink and downlink bit, represents these UE.Such as, support the 50Mbps in LTEUE classification #1(i.e. 100Mbps in the downlink and up link) UE can belong to UE classification #1 group.But this type of group can be identified by the identifier of pre-determining or dynamic assignment, such as, ability group #0.Therefore, the output of matching algorithm belongs to same capabilities group and the therefore identity of one or more UE of compatibility in ability.Another simple example forms the group (ability group #1) of UE, and these UE have similar MIMO ability (such as, 2 × 2MIMO), and no matter maximum downlink and uplink bit rate.Precondition is that all UE in ability group #1 belong to identical RAT, and also supports same frequency band, because otherwise, intercommunication can be impossible mutually.But some UE in ability group #1 accidentally also can support the bit rate of the bit rate being equivalent to ability group #0.Another example still had is the example of ability group #2, and (2 × 2) MIMO operation of communication (transmission/reception) while ability group #2 comprises on two carrier waves being supported in and belonging to two different frequency bands, every carrier wave and every carrier wave are equivalent to the UE of the maximum downlink/uplink bit rate of LTEUE classification #1.Above-mentioned example illustrates that identical UE may can belong to several ability group, this is because the UE belonging to ability group #2 also can belong to ability group #1 and #0.Suppose in certain time, only at use carrier frequency when this type of UE operates in ability group #2, UE can also operate when needed simultaneously in ability group #0 or #1.But, when using group's #2 ability completely, the UE operation not included in ability group #0 and #1.
Ability group also can comprise the UE supporting similar RAT, such as, supports the ability group #3 of WLAN, LTE and WCDMA.Similarly, another ability group #4 comprises the UE supporting WLAN, WCDMA and GSM.Also ability group can be created according to the UE data rate request being coupled to COS.Such as, the interesting UE carrying out broadband connections (High Data Rate download) is classified in a group of UE, and these UE can support very high data transfer rate (such as, 100Mbps or higher), no matter and basic technology.Such as, this type of ability group #5 can comprise UE:(2 × 2 can supporting any following characteristics) MIMO double small district HSDPA(namely, received by 2 WCDMA carrier waves) and LTE classification #1.Therefore, support that the UE of normal WCDMA and GSM can not be included in ability group #5, this is because it can not provide required ability, and only support that the UE of LTE classification #1 can be included in this group.

In one embodiment, network node transmit self-organizing " paging " message 250 also can comprise position and/or timing for information about, as compatible UE can meet ad hoc communication and mutual service provision geographical position or time interval.Such as, matching algorithm in the position of the UE networked for self-organizing or its preferences location or can perform mapping between the time, and determines position or the time of the self-organizing networking of this specific compatible group thus.Geographical position can the map in the region shown on the screen of UE show.Alternatively, it can represent in the form of a text message.
In an embodiment of the present invention, network node can once find the coupling group of UE, no matter and in the UE quantity that group comprises, or only in coupling group, the quantity of UE, at any given time or when exceeding certain threshold value N within certain duration, determines assembling self-organizing " paging " message 250 and sends it to UE.After this advantage of an embodiment that reduces signaling consumption.At any time, network node also can be dismissed or group (such as, interpolation newcomer or when deleting existing member) is mated in temporarily forbidding or renewal, and again indicates this to operate by sending class beep-page message to UE.Self-organizing " paging " message sends by signal and once, several times or regularly sends.
When UE1 and UE2 is received from tissue " paging " message 250, therefore one of they are any can receive the identity of another compatible UE in message 250 based on them, start with the self-organizing network of the opposing party set up 260.Foundation can use recent technological advances self-organizing link establishing method to complete.After self-organizing link built vertical 260, UE1 also can send additional details to UE2 on the specific special or common share communication link of UE.Such as, UE1 can broadcast greeting (HELLO) message networking known from recent technological advances self-organizing, and message comprises the UE identity of oneself identity and coupling and optional service identities.
Alternatively, UE1 can clearly ask UE2 to avoid using some frequency channels in order to avoid cause interference (so-called " soft access control ").Situation when this is UE1 understanding UE2 ability.The coupling group information that network node provides is considered to be suggestion.Therefore, whether UE decides in its sole discretion is that ad hoc communication uses " suggestion " coupling group knowledge.Therefore, in this example, UE1 can determine not communicate with UE2, this is because they are not exclusively compatible in desired ability, or because UE1 wants to set up self-organizing network with the UE of more preference.May be that UE1 also belongs to another matching capacity group.Therefore, UE1 can even attempt setting up ad hoc communication with the UE belonging to another ability group.Alternatively, in order to set up ad hoc communication link, UE1 can select arbitrarily another UE.
